UNIT KEYS
Options Key
There are many user programmable options under the
OPTIONS key. The OPTIONS key is used to scroll
through the list of options by repeatedly pressing the
OPTIONS key. After the selected option has been dis-
played, the ↑ (UP) and ↓ (DOWN) arrow keys are then
used to change that particular option. After the option
is changed, the ENTER/ADV key must be pressed to
enter the data into memory.
Many of the “Options” displayed are
only programmable under the “Ser-
vice Mode” and not under the OP -
TIONS key. Options only program-
mable under the “Service Mode”are
noted in the details describing the
option.
